Abstract

The new metastable compounds BaSr₂Y₆O₁₂ (I), BaSr₂Er₆O₁₂ (II) and BaSr₂Tm₆O₁₂ (III) could be prepared with high temperature reactions (CO₂-Laser). The X-ray single crystal investigations lead to hexagonal symmetry, space group Ch-P² _6h-P6₃/m; lattice constants: I: a= 1029.9 c = 340.9 pm II: a = 1027.7 c = 338.5 pm III: a = 1021.5 c = 337.6 pm The crystal structure the formation of the compounds and the range of stability are discussed.
